PDF to Book

Black & White Images on PDF to Book

Hi,

This is not my first book with Blurb but it will be the first using PDF to Book with Adobe Indesign. The wll be a mix of colour and B&W photographs and I understand that for colour images, CMYK is the profile to use (PSD format 300 DPI). 

My question is what is the profile for B&W pictures? I really want to avoid those horrible colour casts…

Many thanks

If you have a look at this thread it should give you some ideas. http://forums.blurb.com/forums/10/topics/8249  I use just sRGB tiffs for the colour images as Blurb will convert it, and I use the workflow in the forum thread to produce the B&W tiffs. It works for me but, as always I would recommend making a small test book with both colour and B&W images bfore committing your main book to print. The only other thing that I do is apply a very small lift to the midtones but that is probably just my personal preference. Hope that this helps.

Thank you very much for your response Robin…

I’ve also came across with this : http://www.blurb.com/guides/color_management/prep_bw_pdf and I’ll decide which one to use by doing some tests.

All my B&W images are in grayscale format, do I have to convert to RGB prior to CMYK or is it possible to convert straight to CMYK?

Regards

No, if you follow the workflow you are converting greyscale to a custom CMYK as part of the process to get an image that will print as neutral as possible. Just leave it like this. CS5 will warn you that you are using a non standard conversion but just ignore the warning.
